Tetrahydrofurfuryl-nu-methyl carbamate



United States Patent TETRAHYDROFURFURYL-N-IVIETHY L CARBAMATE Archie J. Deutschrnan, Jr., Columbus, Kans., and Willard C. Bull, Joplin, Mo., assignors to Spencer Chemical Company, Kansas City, Mo., a corporation of Missouri No Drawing. Application December 1, 1953, Serial No. 395,599

2 Claims. (Cl. 260347.4)

This invention relates to the discovery of a new and useful compound, tetrahydrofurfuyl-N-methyl carbamate, represented by the following formula 0 s H menoon o Example 79.0 (0.9 mole) 1,3-dimethylurea and 918 gms. (9.0 moles) tetrahydrofurfuryl alcohol were heated together at 200 C. under autogenous pressure for 17 hours. Fractional distillation of the reaction mixture gave 29.0 gms. of product boiling at 100105 C./2 mm. Hg, M. P. C., n =1.4639.

What is claimed is:

1. Tetrahydrofurfuryl N-methyl carbamate having a boiling point of -105 C./2 mm. Hg and a melting point of -70 C.

2. A method of preparing tetrahydrofurfuryl N-methyl carbamate consisting of heating 1,3 dimethyl urea with an excess of tetrahydrofurfuryl alcohol at a temperature of about 200 C. and separating the tetrahydrofurfuryl N-methyl carbamate from the reaction mixture.
